US Patent 11259049 Area-based processing method and apparatus for 360-degree video

A 360-degree image encoding method that is performed by an encoding apparatus according to the present disclosure comprises the steps of: obtaining a two-dimensional (2D) space picture with respect to 360-degree video data; deriving motion constrained tile sets (MCTSs) for configuring a sub-picture from the 2D picture; configuring the sub-picture including the MCTSs based on the MCTSs; and encoding the sub-picture so as to output encoded image information, wherein the MCTSs are arranged in the raster scan order on the sub-picture.
